Headwind Hunter iPhone App - Aerospace Avionics for Your Vehicle

Headwind Hunter makes aerospace technology once only reserved for pilots available to all. Headwind Hunter can increase fuel efficiency up to 20% by knowing when a fuel wasting headwind exists, and allowing you to intelligently reduce speed - only when it makes sense. This powerful tool is the latest in adaptive fuel efficiency technology. By sourcing hyper-local weather data, Headwind Hunter creates a virtual airspeed sensor in your car and let's the driver visualize the wind relative to their vehicle direction. The app provides a top down view of wind direction and magnitude on a vehicle. It's just the beginning of next generation aerodynamics.

By sourcing hyper local weather data, Headwind Hunter creates a virtual airspeed sensor that increases fuel efficiency up to 20%. Visualize real time aerodynamic drag force and see headwind or tailwind relative to vehicle direction.

Headwind Hunter FEATURES:

* real time calculation of aerodynamic drag force on your vehicle* historical chart of aerodynamic drag force on your vehicle (real time in orange, average drag force in white)* rotating wind direction indicator - from a top down view* rotating RED and BLUE wind direction arrows. RED arrows light up for headwind, BLUE arrows light up for tailwind* estimated Airspeed "A" and Groundspeed "G" indicator at the center of the rotating arrows* near real-time wind data from local weather stations

ROTATING LABELS:

* NOW PAYING label is the amount you are currently paying per gallon of fuel due to headwind/tailwind effects (i.e., if you purchased gas at $2.99/gallon and experience a 10% MPG PENALTY, your effective fuel cost is $3.29. OR a 10% MPG BOOST during a tailwind results in a $2.69 fuel cost)

* MPG PENALTY/MPG BOOST label is the percent change in miles per gallon due to a headwind or tailwind. PENALTY/BOOST is calculated with respect to zero headwind or tailwind at your current ground speed.

* NET WIND EFFECT label is the net accumulated fuel cost penalty or savings from wind. A net cost penalty is a positive number, and net cost savings is shown as a negative number. Net Wind Effect is only calculated when the app is open and calculated with respect to MPG at your groundspeed without wind.

* HEAD WIND DETECTED: SLOW DOWN! means you currently have a headwind, drive more slowly or safely draft behind another vehicle to improve fuel economy.

* "TAILWIND DETECTED: SPEED UP!" means you currently have a tailwind (nice!). Either drive faster with a minimal fuel economy penalty to make up time or keep the same speed and increase MPG.
